1)

Issue the MODE SENSE command and when a RECOVERED ERROR is

 

 

 

 

reported, read the "Current" value in the changed MODE SELECT or MODE

 

 

 

 

SELECT EXTENDED parameter.

 

 

 

2)

If the value actually set in that parameter page is within the INIT's permissible

 

 

 

 

range, perform recovery method 0.

 

 

 

3)

If the value actually set in that parameter page is not within the INIT's

 

 

 

 

permissible range, adjust the value specified in the parameter and issue the

 

 

 

 

MODE SELECT or MODE SELECT EXTENDED command again.

 

 

 

 

 

 

 

10

1)

Issue the START instruction using the NOTIFY Primitive (ENABLE

 

 

 

 

SPINUP).

 

 

 

2)

When the START/STOP UNIT command is terminated abnormally, perform

 

 

 

 

recovery method 1.

 

 

 

3)

When the START/STOP UNIT command is terminated normally, reissue the

 

 

 

 

original command (Retry).

 

 

 

 

 

 

 

11

1)

Wait for formatting (FORMAT UNIT command) to be completed.

 

 

 

2)

Reissue the original command (Retry).

 

 

 

 

 

 

 

12

1)

Set the "Number of Retries" value in the MODE SELECT parameters at the

 

 

 

 

"Default" value.

 

 

 

2)

Reissue the original command (Retry). (Note)

 

 

 

3)

If the error is not recovered from after the first retry, issue the REZERO UNIT

 

 

 

 

command.

 

 

 

4)

Reissue the original command (Retry). (Note)

 

 

 

5)

If the error is not recovered from, perform one of the following.

 

 

 

 

− When the sense key is "HARDWARE ERROR [=4]," perform recovery

 

 

 

 

method 1.

 

 

 

 

− When the sense key is "MEDIUM ERROR [=3]," implement alternate

 

 

 

 

block allocation processing (shown in Section 6.4).

 

 

 

Note When the original command is the REASSIGN BLOCKS command, it may

 

 

 

 

be necessary to reconfigure the defect list. For details, see the description of

 

 

 

 

the REASSIGN BLOCKS command (Section 4.3.2).
